The first thing to be understood is to drop the idea of trying to meditate for anything. Â If you begin by desiring quieter thoughts or more relaxation or any other things you are setting yourself up for failure.
Meditation is the process of becoming aware of what is in this moment. Â Whatever is, is perfect.
If, as you begin to watch, to look in, to become aware, you notice thoughts happening, great! Â Thoughts are happening. Â I will simply be aware as the thoughts pass through.
If you notice feelings of joy arising, great! Â I will watch joy.
Simply notice what is, and accept it from your heart, with no expectations for any particular state of being.
Its not a matter of reaching Kundalini its a matter of ascending the Kundalini serpent to pierce the 7 main chakras. The Kundalini (if you feel you are ready) can be awakened through Kundalini yoga and use of Chakra Chants. This meditation http://www.angelfire.com/empire/serpentis666/Full_Meditation.html Is the one that awakened kundalini for me. I must warn you though that it is not something you want to do unless you know that you are ready and know void meditation.
Kundalini is a journey not a destination. you meditate for the sake of meditation and if you reach Kundalini then it is good, if you do not, that is also good.
Do not spend your time searching for it just accept it if you do find it.
